[Q] Turn Down Brightness

I was wondering whether there were any apps which would allow you to lower the brightness beneath the lowest setting available in settings? My brightness is at the lowest setting and I reckon I could lower it further and not be disappointed whilst saving myself some battery.
Any ideas?

I'd like to know this too. I've got my brightness at 0% using the "Brightness Level" app, but if I'm browsing I notice that if I sit on the screen for about 30 seconds, the screen will dim further beyond the supposed minimum.

Voodoo has an ultra low brightness mode.

Really? I used to run Voodoo beta 4 on Tayutama's JM8 ROM, but didn't see that feature and it's not mentioned in the changelog:
http://project-voodoo.org/changelog
I'm currently using Hardcore kernel which seems to be faster (probably because of the No-RFS Advanced option I'm using)

Old Voodoo for Eclair had a low brightness mode, but ultra low brightness will be in future Voodoo release, in approx ~1 month
And of course it will be configurable (or it's as useful as annoying!)

Dimmer App
I use the Dimmer app available from the market. This takes brightness down to a third of the default minimum...

Screen filter from the market works really well, you can set it more or less to completley black if you want. But i am not sure if it helps saving battery. But as far as i know how AMOLEDs work it should help...
Anybody else using it?

ScreenDim

New on the Market:
https://market.android.com/details?...mkub21lZ2FjZW50YXVyaS5TY3JlZW5EaW0uVHJpYWwiXQ..
"Is your minimum screen brightness still too bright? Dim your screen below what your device normally permits for comfortable use in darker environments, reading in bed, amateur astronomy, etc.! No root required."
I find this app indispensable for comfortable reading at night.

Thank you so much for this, I was just thinking last night that even the dimmest setting on the A100 was still to bright

I'm the ScreenDim developer. Screen Filter is free and clever, but it doesn't do the same thing as ScreenDim, at least not on LCD devices. Screen Filter basically just alpha-blends a dark box over the screen, without lowering the backlight level below what the OS normally allows. The result is that Screen Filter lowers the contrast and the color resolution, and in a dark room, the blacks will be gray because of the backlight shining through them.
ScreenDim allows you to both lower the LCD backlight level below what the OS normally allows on many devices and, if that's not good enough, to control the contrast just as Screen Filter does. Furthermore, because ScreenDim allows you to lower the backlight level, it will save on batteries in a way in which Screen Filter will not, again on LCD devices. (On OLED devices, there is much less of a difference.)
Moreover, my testing on my Archos 43 indicates that Screen Filter lowers the 2D rendering performance by about 30%. ScreenDim at 100% contrast shouldn't affect the 2D rendering, and even with the contrast adjust, I couldn't measure a noticeable 2D performance loss.
For real free alternatives to ScreenDim on backlit devices, there are AdjBrightness and my RootDim, both in the Market. Both require root, however. And ScreenDim's dual brightness-contrast adjustment feature is found in neither.

+1 for root dim, I use it and it works well on this tab and my atrix

be careful not to set it to 1 because its turns off the screen but the tablet is still on. i got stuck trying to find the slider to slide it back so i can see the screen again. nice find though.

Tapping random places on the screen should quickly restore the brightness.
Also, if the tablet has volume buttons, you can adjust brightness with them.
Once you figure out what the lowest you can go is, go to Options | Set minimum brightness. Then you won't have this worry any more.

Love screen filter it works great and its free, super simple, plus pop notification bar too. Awesome app. Screen filter is

ahem. I'm not sure exactly where those buttons were when I needed them to try to get the brightness restored, but I couldn't find them on two occasions. I had to hard power off.
Great idea but it won't work for me unfortunately. I want something that will turn my tablet into pure darkness except for a small, dimly illuminated, clock on the screen. No matter what I find, an app always has too much backlight on and it bothers me when I'm trying to sleep.
If only I could get this app to interact with my alarm clock app somehow!

Status bar
Is there any way to remove the status bar icon of the ScreenDim?
I thought the app was designed to reduce distraction while using a device, but the icon being in the most prominent spot (upper left corner) draws attention constantly.

How to dim the GN screen even more?

I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?

Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.

Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.

CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.

i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.

Thanks for all the ideas. I went with the easiest one, Screen Filter.

AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.

Display Brightness App

I posted this before when all the SGS3 variants were under one forum. Now that they're locked, I just wanted to post this here as I know a lot of people liked the app. I use it everyday.
One thing I definitely miss on SGS3 coming from SGS1 and SGS2 was the ability to change the brightness setting from from the top of the notification bar. You were able to slide your finger left to right and be able to change the screen brightness.
Display brightness can do something similar and thought I'd share as I am sure a few of you might also miss the old feature. You can set a screen brightness slider anywhere on the screen and change its transparency. It works a treat to be able to change brightness quickly and efficiently. I set mine to be on the left side of the screen horizontally, and set transparency to 0 so it cannot be seen. Then when I need to change brightness quickly, I just slide the bar up or down. There are quite a few options and different sizes you can choose. Also, you can set it so that there is a one second delay. This helps to avoid touching the bar by accident and changing brightness on you.

Have it installed and really like it.
One problem I'm having is that I set it to Enable the Indicator on my screen, and it periodically turns off. A bit frustrating. But other than that, it's great.

I get the error trying to install apps every time I flash cm10 and then go back to stock. If that's the case youd notice it trying to install other apps on the market. Either case it's a market problem or the rom you're on. I normally fix by clearing market data as well as google framework data too. Then reboot and I can install apps again. It doesn't sound like an app problem though
Also the indicator shutting off I have not seen before. That could be a result of task manager app or something shutting it off somehow

I thought about that. If so, it is the system manager, because I do not run task managers.
I do have System Tuner...have nothing set in it's killer. I did set this app as excluded (which my understanding is that excludes apps from availability to kill). I think maybe it did help, but did not cure the issue.

Ultimatum rom lets you change brightness from the top. However the min brightness doesn't go low enough on this phone. Too bright in dark rooms

I use another app called screen filter for the darkness issue. Check it out! You can then make the screen MUCH darker depending on preference. I agree, the screen does not go low enough on this phone especially at night when in a dark environment.

Brightness issue

First things first, i want to APOLOGIZE if this is a repost as i haven't been able to find this issue else where unless im just that blind.
Im running "A Guru'd NIGHTLY, Themed, Loaded, And Ready To Roll!!! (Update 7-24-12)
android 4.4
t989uvle1
3.0.8-perf-g4ea71fo [email protected] #1
9-20120724 nightly.
When brightness is set to max, and auto brightness is turned off the following happends.
Overall brightness seems a little dimm, not a whole lot but enough to notice, however when i slide the notification slider down the bottom of the screen gets brighter, also when in email or messaging app, when the keyboard is open the top half of the screen become brighter, were talking about about 10-15%
Is there a setting i can modify in a file that represents the overall total allowable brightness, i just figure if the screen becomes brighter under certan circumstances then it might be possible?
Also the color almost seems a little be off, like white is not quite white. Annoying for extended reading sessions.
tried changing the mDNIe settings but nothing changes.

Really? Mine does the same thing. I figured it was the ROM cause stock I haven't noticed it. My HD2 did it as well. I honestly think it has something to do with battery saving. I noticed if there is a lot of white showing it dims it a little, then when there is a dark image, it increases the brightness.
